RESUMEN
Objective To investigate the correlation of diabetic skeletal muscle disease with macroangiopathy, and to explore the related genes of Shenqi Compound Recipe (SCR) in preventing and treating diabetic skeletal muscle disease by using gene chip technique, thus to reveal the molecular mechanism. Methods KKAy mice were fed with water containing nitri oxide synthase inhibitor of Nω-nitro-L-arginine methyl ester ( L-NAME) and high fat diet to induce the macroangiopathy complicated with type 2 diabetes. The experimental animals were divided into normal c57BL/GJ group, KKAy group, model group, SCR group (in the dosage of 14.4 g·kg-1·d-1) and rosiglitazone group ( in the dosage of 1.33 mg·kg-1·d-1) , 15 in each group. The medication groups were administered the corresponding agents for 8 consecutive weeks just as the modeling began. During the experiment period, blood glucose was monitored. At the end of the experiment, the abdominal aorta and skeletal muscle of mice were taken out for the observation of morphological changes, and differentially expressed genes of skeletal muscle between SCR group and model group, and between model group and KKAy group were detected by gene chip technique. Results SCR had an effect on relieving the atrophy, edema, fracture, and inflammatory changes in the skeletal muscle. There were 198 genes differentially expressed between model group and KKAy group, including 119 up-regulated genes and 79 down-regulated genes. There were 70 genes differentially expressed between SCR group and model group, including 33 up-regulated genes and 37 down-regulated genes. In the two comparison groups, 7 genes ( Celsr2, Rilpl1, Dlx6as, 2010004M13Rik, Anapc13, Gm6097, Ddx39b) showed reversed differential expression. Conclusion Diabetic skeletal muscle disease is associated with macroangiopathy. SCR has preventive effect on diabetic skeletal muscle lesion, and the mechanism may be related to the regulation of Celsr2, Rilpl1, Dlx6as, 2010004M13Rik, Anapc13, Gm6097, Ddx39b gene expression.
RESUMEN
Objective:To explore the effects of Shenqi Compound Recipe on the expression of Cycloxygenase-2 (COX-2)mRNA in aorta in GK rats.There were five groups:GK group,model group,atorvastatin group,Shenqi Compound Recipe group and normal control group.During the experiment periods,each group was administrated correspondent substance respectively for 35 days.Serum concentrations of C reactive protein(CRP)were determined by ELISA.The mRNA expressions of COX-2 in aorta were detemined by reverse transcriptase PCR(RT-PCR).Results:Compared with model group,concentrations of CRP in serum and the mRNA expression of COX-2 all decreased in atorvastatin group and Shenqi Compound Recipe group(P
RESUMEN
Objective: To explore the mechanism of ShenQi compound recipe on preserving vessel endothelium with type 2 diabetes mellitus(T2DM) macroangiopathy in GK rats.Methods: GK rats were randomly divided into Ramipril group,ShenQi compound recipe low dosage group,ShenQi compound recipe high dosage group and Wistar control group.Each group was administrated correspondent substance respectively for 28 days after intra-peritoneal injection of L-NAME and administration of high fat diet for 2 weeks except Wistar control group.To determine ICAM1 by ELISA,ET-1 by radioimmunassay,NOS by chemical shade selection,NO by nitrate reductase method,mRNA expression of ICAM-1 in aorta by real time RT-PCR. Results: Compared with model group,the contents of NO,NOS increased,the ET1 and the expression of thoracic aorta ICAM-1mRNA decreased remarkably in ShenQi compound recipe group(P
RESUMEN
AIM: To explore the anti-low-grade-inflammation mechanisms of Shenqi Compound Recipe(SQCR) in GK rats. METHODS: Specefic pathogen free(SPF) GK rats were divided randomly according to blood glucose level into four groups:Model,Ramipril,SQCR low dosage,SQCR high dosage group and normal Wistar rats(normal control group).GK rats were injected N-?-nitrol-L-arginine methyl ester(L-NAME) intra-peritoneally and took high-fat diet and Wistar rats were injected saline intra-peritoneally and took common diet freely,respectively.In the experiment periods,each group was administrated correspondent substance respectively for 32 days.Serum concentrations of C reactive protein(CRP) and adiponectin were determined by ELISA.Adiponectin mRNA expressions in white adiposed tissue were measured by real time reverse transcriptase PCR. RESULTS:Concentrations of CRP all decreased(P
